ical way and accomplishing the greatest re sults therefrom.

To this end my invention consists in certain improvements over the improved continuous kiln patented July 1, 1902, No. 703,533, and it further consists in the improved construction, arrangement, and combination of parts, substantially as hereinafter fully de claims.

Referring to the accompanying drawings for a more completevexplanation of my invention, Figure 1 Be transverse vertical section on the line Y Z, Fig. 3. Fig. 2 is a longitudinal vertical cent'ralsection on'. the line 1V X, Fig. tal section. I i

A, Fig. 1, represents the kiln in which bricks, tiles, &c., are to be burned.

B B B Fig. 3, are the combustion-chambers below the'kiln-floor opening into the kiln.

O C Fig. 2, are the burners.

D D, Fig. 1, are the pipes for the introduction of fuel into the combustion-chambers.

E, Figs. 1 and 3, are the cross draft-fines.

The fuel introduced into the combustionchambers is burned in suspension, rising at the same time to the bricks, tiles, or other ware, which are set in the kiln to be burned. The pipes for the supply of fuel are run from the top of the kiln down to the combustionchambers, across and below the kiln-floor, where the burners are attached. The burn- Fig. 3 is a longitudinal horizoners can always be repaired at the smallest combustion-chambers running in the same direction as the fire, I require no other connection-flues than the draft-flue. I use the paper partition as is usual in all kilns of this With this system of kiln the fuel is burned in a perfectly natural updraft fashion with the leastpossible amount of waste, as the a draft is carried from the burning ware through the green ware until the heat is dissipated and the gases are too heavy for further use, when'they are allowed to escape through the draft-Hues.

Having thus described my invention, I

claim and desire to secure by Letters Patent- 1. A continuous kiln with combustionchambers extending lengthwise below the kiln-floor in which fuel is burned in suspension, opening into the kiln, parallel with and betweenthe kiln-walls, combined with fuelpipes extending across and below the kilnfioor, and connecting the burners in the said combustion-chambers, substantially as described.

2. 1A continuous kiln comprising combustion-chambers extending longitudinally and below the kiln-floor, parallel with the side walls of the kiln and the semi-annular walls at the ends of the kiln, in which-fuel is burned in suspensiomopening into the bottom of the kiln combined with f uel-pipes running from kiln-floor in which fuel is burned in susp fl,

sion, the top of the combustion-chambers be 1 IOO the combustion-chambers joining dampercontrolled draft-fiues extending across andbelow the kiln-floor, substantially as described.

4. A continuous kiln comprising combustion-chambers running longitudinally and below the kiln-floor the full length of the kiln'and semi-annularly at the ends of the kiln in which fuel is burned in suspension, opening into the floor of the kiln, connecting cross dampereontrolled draft-fiues below the kiln floor; and pipes running to the top of the kiln for the purpose of supplying fuel to the combustionehambers, substantially as described.

5. A continuous kiln having combustionchambers extending lengthwise and directly under kiln-floor parallel with the inelosin g
